Description
This device consists of a low-power voltage
comparator designed specifically to operate from
a single supply over a wide range of voltages.
Operation from split power supplies is also
possible.
This comparator also has a unique characteristic
in that the input common-mode voltage range
includes ground, even though operated from a
single power supply voltage.

Notes:
(1)Output voltage can be set up to 36 V even if the VCC is lower.
(2)Short-circuits from the output to VCC+ can cause excessive heating and potential destruction. The maximum
output current is approximately 20 mA independent of the magnitude of VCC+.
(3)Short-circuits can cause excessive heating. These values are typical.
(4)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ
resistor between two pins of the device. This is done for all couples of connected pin combinations while the other
pins are floating.
(5)Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected
pin combinations while the other pins are floating.
(6)Charged device model: all pins and package are charged together to the specified voltage and then discharged
directly to ground through only one pin. This is done for all pins.

Notes:

to 30 V without damage.

Notes:
(1)At the output switch point, Vo 1.4 V, RS = 0 Ω with (VCC+) from 5 V to 30 V, and over the full input common-mode range
(0 V to (VCC+) 1.5 V).
(2)The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of
the state of the output, so there is no load charge on the reference of input lines.
(3)Positive excursions of the input voltage may exceed the power supply level. As long as the other voltage remains within the
common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than
0.3 V (or 0.3 V below the negative power supply, if used)
(4)The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be
obtained.
